Case Study: Green IT in manufacturing

I came across this story about IT in manufacturing where a US company, Eaton, has installed six of its uninterruptible power systems (UPS) in its data centres, helping the company save roughly $75,000 a year in energy costs.

The story, carried by Reuters from content by GreenBiz.com, recounts that Eaton has achieved efficiencies at its Cleveland-based data centres by investing in VMware virtualisation technology, which has enabled Eaton to remove 670 servers. That means the company has reduced its annual power consumption by more than 4.4 million kilowatt-hours and cut its annual carbon dioxide emissions by 2,685 metric tons.

By installing its own systems, Eaton has managed to reduce its own energy usage and so reduce its costs. A clear case of 'talk green, mean lean.'

The UPS project from Eaton is a good point. But we shouldn't forget that :
- 1 transaction by 4 don't have any sens,
- 15 % servers are running apps that are not used,
- that's the software layer that is driving power equipment needs.

That said, UPS efficiency is good. But we need to act in priority on the software layer and governance.
